She told the BBC she believed Devon and Cornwall Police "missed dozens of opportunities to prevent the stabbing".

Ms Perason will now be talking about her experience to the trainees on a course developed by the Paladin group - which supports victim, ensures they're getting the protection they need, and helps collect evidence to bring the stalker to justice.

Recalling the attack, Ms Pearson said last month: "The first I knew about it was when I was stabbed in the back. I turned and saw it was Joe.

"I saw his eyes and he looked absolutely furious. The first blow pushed me to the floor and he kicked me and was trying to drag me along into the Catacombs. That was where it was going to end. I tried to get free. I felt another kick and stab from behind.

"I thought this is going to go on until I am dead. He was deranged and so evil. I had six stab wounds in total on my back.

"I remember seeing the scissors and turning my head and seeing them come down. I saw his eyes were full of murder. He definitely wanted me to die.

"I was struggling and screaming and pleading. I remember saying, “Please, Joe, no”. He never spoke to me throughout the whole thing."
